They suffer from the social interactions , the stereotypic behaviors and verbal skills impairments and these problems can lead to withdrawal and other behavioral problems.

We study a bargaining situation—an indefinitely repeated investment game in which Player A decides how much of an endowment he wants to invest whereas Player B decides how much of the then tripled investment she wants to return. In two studies, we show that participants in the role of Player A make substantial investments (“trust”), those in the role of Player B return substantial parts of the ...

Human dynamical social networks encode information and are highly adaptive. To characterize the information encoded in the fast dynamics of social interactions, here we introduce the entropy of dynamical social networks. By analysing a large dataset of phone-call interactions we show evidence that the dynamical social network has an entropy that depends on the time of the day in a typical week-...

As empirical work in identifying social effects becomes more prevalent, researchers are beginning to struggle with identifying the composition of social interactions within any given reference group. In this paper, we present a simple econometric methodology for the separate identification of multiple social interactions. The setting under which we achieve separation is special, but is likely t...

Social exclusion is known to cause alterations in neural activity and perceptions of social distress. However, previous research is largely limited to examining social interactions as a unitary phenomenon without investigating adjustments in neural and attentional processes that occur during social interactions. To address this limitation, we examined neural activity on a trial-by-trial basis d...
